| Abstract: | The variational laws of grain hardness on solid rocket motors and the hardness, thestrength and the extensihility of HTPB propellant piece in the storage period are studied.Themathematical models and the regression equation groups of the grain hardness strength relation, theextensibility storag life relation have been built in this paper. The grain life on solid rocket motors arepredicted by means of the method. |
